Permafrost region airfield runway structure and construction method thereof
The invention discloses a permafrost region airfield runway structure and a construction method thereof. The runway structure sequentially comprises an epoxy resin concrete wearing layer, a geocell solidified soil layer and a geocell compacted soil layer from top to bottom, and the geocell compacted soil layer is arranged on a permafrost road foundation bed, wherein the geocell solidified soil layer comprises a geocell and cement-water glass foamed solidified soil filled in the geocell; and the cement-water glass foamed solidified soil is a solidifiable mixture which is prepared by stirring soil obtained in situ, taken as a main material, and a soil curing agent ordinary Portland cement and water glass, which are taken as secondary materials, and water and a foaming agent which meet the requirements of fluidity and hydration reaction process. Compared with runways constructed through a traditional construction technology in permafrost regions, the airfield runway constructed by the method has the advantages of good thermal performance, strong frost heaving resistance, small post-construction settlement and differential settlement, low construction cost, no cracking of the runway surface, long service life and the like.
本发明公开了一种多年冻土地区机场跑道结构及其施工方法，该跑道结构自上而下依次为环氧树脂混凝土磨耗层、土工格室固化土层和土工格室压实土层，所述土工格室压实土层设置在多年冻土道基基床上；其中，土工格室固化土层包括土工格室和填充在土工格室内的水泥‑水玻璃发泡固化土；其中水泥‑水玻璃发泡固化土是以就地获取的土为主要材料，以土体固化剂普通硅酸盐水泥和水玻璃作为次要材料和满足流动性和水化反应过程所需要的水以及发泡剂，经过搅拌的可固化拌合物，与多年冻土地区传统跑道建设技术相比较，利用本发明建造的机场跑道具有热工性能好、抗冻胀能力强、工后沉降及差异沉降小、施工造价低、道面不开裂、服役寿命长等优点。
